How about a fozen whisky slush? since we went from winter (seriously pulled my winter coat out of the car on Monday...and it's been 90 yesterday and whatever today is, it's summer before the solstice! Freeze your favorite lemonade or lemonade/tea and add 1 part whisky to 3-4 parts lemonade or tea.

Other good uses for a non-favorite bottle would be a whisky sauce for bread pudding or a whisky sauce for a steak (and set it on fire!)
